Mark Rutte wants large rise in military spending as threat from Russia will remain ‘even when war in Ukraine ends’

Russia will remain an imminent threat to Nato even if there is peace in Ukraine and the western alliance has to increase its air and missiles defences by 400% as a result, the head of the organisation will say on Monday.

Mark Rutte, who is visiting the UK and meeting the prime minister, Keir Starmer, is expected to outline why it is necessary for allies to agree a dramatic increase in military spending to 5% of GDP at a summit in The Hague later this month.
